New 320d makes peak power at 5,500rpm

Wowzers hardly any different now to the Rev range of petrols who’d have thought it - years ago 3k and all was done now as per the article and journalist it headbuts the limiter

Engineering superb and 6.8 seconds to 62mph which will be the company car choice for many.

Think it may be a typo.

Having watched a few videos on YouTube the new 320d (auto at least) appears to change around 4250 RPM on full throttle. Not sure if putting it in manual mode will allow it to rev out to 5500 RPM though.

5500rpm does seem really high for a diesel for sure. The torque figure is the same as what my old V8 M3 made(only it comes in miles earlier in this). Compelling figures and I'd like a go in one because I did find the 20d engine in my 2009 520d to be a bit rough and ready. 10 years in engine development is a long time though...so I guess this could be silky smooth in comparison.

Had a quick search and it states that peak power is 4000rpm for these...so it is definitely a typo I think.

Pretty impressive as that's about the same performance as the 3.8 E-type! (though that was almost 60 years ago)

Bet it still sounds like tumble drier full of bricks when you start it.

That would be my worry in fairness and it is virtually impossible to get a diesel engine to feel/sound smooth on start up/at idle.

do all new diesels sound this bad? My transit (okay it's a ford I know) sounds like a tractor, okay the last van was a v6 so not fair to compare but I'm sure the preceding Mitsubishi 2.8 & vw 1.9 4cyl diesels never sounded anywhere near so bad.

Still will be an unreliable, small, cramped, over priced pile of junk like the predecessors before it.

There are still some awful-sounding ones. The 1.9 MB lump makes a terrible racket. There was a new GLC idling outside the supermarket yesterday when I went in and still idling when I came out. So it was warmed up. Jeez it really did sound like a tractor.

I had a E with that engine as a loaner and could clearly hear the engine in the cabin at all times other than on trailing throttle. And I could fel the vibrations and fizzing through the pedals and wheel. I think it's because they run such massive compression ratios. In the case of MB they seem to be getting louder from the outside, if anything.

The noise makes my teeth itch.

Thankfully they won't be around for much longer. Diesel is finally going where it belongs, trucks and trains. Petrol, hybrid and electric for cars only and I cannot say I am sorry to see diesel cars getting harder to get - as a car lover I just cannot abide the things. I even have a clause in my will for my final journey to be a petrol powered hearse - not a diesel - that is how intensely I dislike them.

I don’t think it is - 4K revs is the old 320d single Turbo this new 320d sane power but they use sequential turbos like the 535d so instant power low down and then the big turbo coming in strong.

But that surely makes the Cerb feel so much more special when you drive it?

In my F10 535d 9 years old this Dec the engine is quiet inside the cabin maybe it’s the I6 and sound deadening.

For the U.K. electric trucks would be ideal. We don’t have massive range requirements as were a tiny island with limitations on how long drivers can drive. Maximum torque for standstill no gears and the Tesla does 5.5 seconds to 62mph just the tractor not the 40tonnes. We will hopefully see ULEZ full of them.

I've had a GLC350d from new(3 litre V6 diesel) and the noise it makes at idle has always annoyed me. It also has an annoying very slight vibration on the throttle pedal when you move off.

I do think that a torquey diesel engine does suit a heavy SUV, but I just wish a diesel engine could be made to feel smooth(in fairness the diesel engine in mine has been around since 2005 though).

I've read really good things about the new 3 litre straight six diesel that Mercedes do now, so I'm hoping that has moved the game on a bit.

Haha, lets not let facts and truth get in the way of a good biased rant.

Here we go again....

Good to see diesel is far from dead.

Wiki and all the reviews I've looked at online state max power at 4000rpm. The 2 litre turbo 330i only makes max power at 5000rpm so there's no way that the diesel is higher than that.

Is Wiki talking about the press release car from a few days ago the twin turbo 320d or the old 320d single turbo?

Also isn’t Wili just updated by anyone?
